GAS-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 398,805, dated February26, 1889. Application filed July 2'7, 1888, Serial No. 231,233. (Nomodel.)

a new and useful Improvement in Gas-Extinguishers, of which thefollowing is a specification.

details of combination and construction, substantially as illustrated inthe drawings,hereinatter described, and subsequently pointed out in theclaim.

Figure l is a side view, partly in section and partly in elevation,illustrating my invention. Fig. 2 is a detail view, partlyin section,

further illustrating a part of the apparatus.

It has been found by experience that many awkward and ignorant personshave blown out the burning gas in their rooms without shutting thestop-cock. This has frequently caused the loss of life. It is to shutoff the flow of gas as soon as the flame is extinguished, and so preventany such evil consequences, that my invention has been devised. In theexample of my invention here given it is attached to a bracketgas-light. It may light.

(l H I J designate the bracket.

1) designates the stop-cock, and Ii the bu ruer; E, the flange againstthe wall; U, the wall, and L the glass globe.

In the joint G H is placed a key, F, perforated as illustrated, whichwhile in the position illustrated in Fig. 1 gives free egress to turnedon the stop-cock D, raises the weight M a little to allow the weight Qto come down on It and close the circuit. This energizes the magnet,which at once draws up the armature B and the key F and allows the gasto come to the burner. When the burner is alight,
